newbie question here. i just bought 1/2 ton of "fireside ultra" premium pellets at home depot yesterday. while loading on cart i noticed bags were a bit wet. we had frost the previous night so i assumed they were just brought in from outside and frost was melting. got them home, dropped a bag in the hopper and got a fire going. no problem. woke up this morning and took a look in the hopper and up near the top there is condensation accumulated all along lip? i am new to this but i know that's not good. also i noticed bag had alot of sawdust in it. after doing a search here i did find you really have to clean them before you burn them. is that about correct? or does the brand have more to do with the quality ? anyway i was concerned about whether or not i got a wet batch of pellets or is this normal to some degree?
